' MEASURING-TOOL.

Specification of Letters Patent.

Patented Aug. 18, 1914.

Application filed December 18, 1913. Serial No. 807,515.

To all whom it may concern:

. Be it known that T, WILLIAM G. Mnrnns, a citizen of the United States, residing at Mitchell, in the county of Davison and State of South Dakota, have invented a new and useful Measuring-Tool, of which the following is a specification.

This invention relates to measuring tools and more particularly to a pocket rule adapted to be folded compactly so as to be conveniently carried but which can be used as a triangle and as a bevel, the said tool being made up of members designed to nest together when the toolis folded but which will shift relative to each other when the tool is opened out, thus-to dispose the parts of the tool for use either as a bevel or as a triangle.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the in vention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings: Figure 1 is a perspective view of the device folded for use as a rule. Fig. 2 is a plan view. Fig. 3 is a section on line 14-13 Fig. 2. F ig. 4 is a plan view showing the tool partly extended to form a bevel. Fig. 5 is a view showing the tool fully extended to form a triangle.

Referring to the figures by characters of reference 1 and 2 constitute similar oppositely disposed rule members having their ends beveled at the two members being oppositely disposed and being hingedly connected at the inner ends of the bevels formed at one end of the tool, this hinged connection being indicated at 3. Those ends of the members 1 and 2 which are hingedly connected are solid while the opposed ends of the members are hollow inasmuch as said members are channeled longitudinally from said ends to points adjacent the hingedly connected ends. The channels have been in dicated at 4.

Pins 5 are txended transversely through the channeled portions of the members 1 and 2 at points near the open ends of the channels and mounted on these pins are the outer ends of intermediate members 5 and 6. The inners ends of these members are cut off at right angles and are hingedly connected as shown at 7 while the outerends of the inner members are cut off at 45 as shown at 8. Thus it will be seen that when the members 5 and 6 are brought into alinement with each other, their inner ends will come together. while their outer or beveled ends 8 will abut against theinner walls of the channels in the members 1 and 2. Thus a triangle will be produced. Each of the members 5 and 6 has a rib 9 extending along both its upper and lower face at the outeredge thereof, the thickness of these ribs being equal to the thickness of the walls of the channels 4 so that the upper and lower faces of the ribs will lie in the same plane with the upper and lower faces of the members 1 and 2. Furthermore the members 1 and 2 are cut away longitudinally, as shown at 10. Consequently, when it is desired to collapse the tool, the hingedly connected ends of the members 5 and 6 are pressed inwardly toward the hinge 3, thus causing the members 5 and 6 to swing into the channels 4, at the same time drawing the beveled ends of the members 1 and 2 toward each other. By then swinging said members 1 and 2 together, the members 5 and 6 will become housed within the channels 4, ribs 9 fitting snugly within the cutaway portions 10, as shown clearly in Figs. 1 and 2. The hinges 3 and 7 as well as the connections between the members 1 and 5 and 6 and 2 are such that considerable friction will be produced when the members are shifted and, consequently, the members will remain in any positions relative to each other to which they may be adjusted until forcibly shifted out of such positions. 1

It will be obvious that by providing graduations on the members 1 and 2, as shown, the tool can be used as a rule. y swinging the members 5 and 6 outwardly into alinement, the members 1 and 2 will be spread apart so that all of the members will assume the relative positions shown in Fig. 5, thus producing a triangle. By partly folding the members 5 and 6, as shown in Fig. 4, any desired bevel can be obtained.

Importance is attached to the fact that all of the members of the tool are constantly connected by means of their pivots,-it beingunnecessary at. any time to detach one mein-. her from the other.

What is claimed is a I I l. A device of the class described includ ing opposed measuring members hingedly connectedat one end, and having their faces lying in the same planes, interposed mem-. bers hingedly connected together at one end and hingedly connected at their other ends to the first named members, said interposed members having faces movable in the said planes being adapted to fold together and, When folded, to nest Within the first named members.

2. A device of the class described including opposed measuring members hingedly connected at one end, interposed members hingedly connected together at one end and hingedly connected at their other ends to the first named members, said interposed members being adapted to fold together and, When folded, to nest Within the first named members, portions of said interposed members being .disposed in the same planes with the corresponding faces of the first named Copies of this patent may be ob'tained for members and all of the members of the device having their faces movable in said planes to either extended or folded positions.

3. A device of the class described including opposed measuring members hingedly coneeted at one end, interposed members hingedly connected together at one end and hingedly connected at their other ends to the first named members, said interposed inembers being adapted to fold together and, When folded, to nest Within the first named members, there being longitudinal ribs upon the interposed members and having their outer faces in the same planes With the corresponding faces of the first named members, said first named members being vcut away longitudinally to receive the ribs when the device is folded.

, In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presenceof two Witnesses.
